IMPROVEMENT m WASHING-MACHINES.

Specification forming part of Letters Patent No. 171,799, dated January 4, 1876; application filed November 9, 1875.

To all whom it may concern:

Be it known that I, LAFAYETTE G. HALL, of Plymouth, in the county of Wayne and State of Michigan, have invented an Improvement in washingMachines, of which the following is a specification The nature of my invent-ion relates to an improvement in washing machines of that class wherein a rubbing-board 'is suspended in a frame in such a manner as to be vibrated in contact with, or contiguous to, a concave of rollers journaled in the lower part of said frame, which is adjustably secured in a vat or tank.

The invention consists, first, in the means of adjusting the frame in the tub or tank; secondly, in the device for suspending the rubbing-board from the main frame, whereby it can be adjusted with relation to the concave of rollers thirdly, in the combination of a soap-receptacle with the rubbing-board, whereby soap can be distributed directly upon the fabric being rubbed.

Figure l is a perspective view. Fig. 2 is a longitudinal vertical section. Fig. 3 is an elevation of one of the frame-elevating ratchets. Fig. 4 is a transverse section through the soapbox and rubbing-board at x m.

In the drawing,A represents a box, trough, or tank, for containing water and the fabrics to be cleansed. B B are the side standards of a frame that may be raised or lowered in the box, the said standards sliding in vertical grooves cut in the sides thereo B is a rock-shaft, journaled through the tops of said standards, at the foot of each of which is a horizontal bar, B the ends of which are connected by transverse girts. O is a concave of ro1lers,whose ends are journaled in the bars B D is a flanged plate, resting on each side of the box, with an inclined ratchet-slot, a, cut in it to receive a stud, b, projecting from each standard, whereby the said standards and their frame and attachments can be raised or lowered in the box as occasion may require. E is a segment-shaped rubbing-board, corrugated er edges of two wooden segments, F, connected at one end by a transverse handle, F. The front ends of said segments are pivoted between the lower ends of two pendulums, G, each having a slot, 0, at the upper end, through which the rock-shaft B passes, and below which they are connected by a girt, G. An adjusting-screw, H, is tappedthrough the middle of the rock-shaft B and has the girt G suspended from its lower end. By means of this screw the rubbing-board may be raised and lowered, to adjust it to the proper distance between its front end and the rollers, as the thickness of the fabric may require. 1 is a metallic soap-receptacle, secured to the front part of the rubbing-board, which is the liquid soap or soap-suds to flow through, and be distributed directly upon the part of the fabric which is being rubbed.

Ido not claim, broadly, the adjustability of the frame in the box, as such frames have been made adjustable heretofore; but

. What I do claim as new is 1. The flanged plates D, each having an inclined ratchet-slot, a, in combination with the studs b on the standards B, as and for the purpose set forth.

2. In a washing-machine, the slotted pendulum G, girt G, adjusting-screw H, rock-shaft B and reciprocating rubbing-segments E, in combination with the standards B, adjustable vertically by means of the slotted plates D and studs 1), substantially as described and shown.

perforated reciprocating rubbing-segment E, the soap-receptacle I, adapted to reciprocate with said segments, substantially as described and shown.
